librelad 875a60f90f LibrePortal v0.1.0 — initial release
A free, open, self-hosted app platform (GNU AGPLv3): one-click app deploys,
Traefik reverse proxy with automatic SSL, rootless Docker support, gluetun
VPN routing, and a web dashboard to manage it all.

Free & open forever to self-host; optional paid hosted services fund it.
See PROMISE.md.
